Believe it or not, it happens with dogs way more often.

About 75% of us are able to say that we fell in love with our canine companion at first sight. This is far more people than those that say they fell in love with their partner at first sight, which is about 27%.

Another funny fact about the study was about the first time we met our pet and partner. Again about 3/4 of us can say exactly when we met our pet. However, only about 1/4 us can say the same for our partner.
